What do you have to know about any segments and angles in a figure to decide whether the figure has line symmetry?

Answers

Answer:

Explained below.

Step-by-step explanation:

When drawing line of symmetry on a figure and reflecting, we have to know that pairs of segments in that figure must have the same length while pairs of angles must have the same measurement. This is to ensure that half of that figure must concise with the other half part of it when that figure is folded across a line of symmetry.

James walked 11 miles in 4 hours. If he walkedthe same distance every hour, how many feet
did he walk in one hour?
A 14,520 ft
B 21,120 ft
C 29,040 ft
D 58,080 ft
Help?

Answers

Answer:

A. 14,520 ft

Step-by-step explanation:

To start off this problem, we need to find how many miles James walks per hour. To do that, lets divide 11 by 4.

$x=(11)/(4)$

$x=2.75$

Next, since 5,280 feet are in a mile, we need to multiply 2.75 by 5,280:

$x=2.75(5,280)$

$x=14,520$

James walked 14,520 ft. in one hour.

How much must you deposit in an account that pays 6.25% interest, compounded annually, to have a balance of $700 after two years? = $

Answers

The compound interest is applied to the remaining balance in the account

each subsequent year.

The amount that must be deposited is approximately $620.07

Reasons:

The given compound interest rate, r = 6.25% = 0.0625

The balance in the account after 2 years, A = $700

Required:

The required deposit, P, that gives the given account balance after 2 years.

Solution:

The following is the compound interest formula to use;

$A = \mathbf{P * \left(1+r \right)^( t)}$

Where;

t = 2 years

We get;

$\displaystyle P = \mathbf{ (A)/((1 + r)^t)}$

Which gives;

$\displaystyle P = (700)/((1 + 0.0625)^2) \approx \mathbf{620.07}$

The amount that must be deposited to give $700 after 2 years is P ≈ $620.07

In a recent Super Bowl, a TV network predicted that 31 % of the audience would express an interest in seeing one of its forthcoming television shows. The network ran commercials for these shows during the Super Bowl. The day after the Super Bowl, and Advertising Group sampled 120 people who saw the commercials and found that 40 of them said they would watch one of the television shows. Suppose you have the following null and alternative hypotheses for a test you are running:1. H0: p = 0.53 Ha: p ≠ 0.53
2. H0: p = 0.53 Ha: p ≠ 0.53
Calculate the test statistic, rounded to 3 decimal places.
